Setting up a scene with camera position and view

Subject: Setting up a scene with camera position and view Sun 12 Feb - 0:14

Hi,

in OpenSCAD you can set up a scene by setting the special variables for camera position and view ($vpr viewport rotation, $vpt viewport translation and $vpd viewport camera distance). I tried to set these special variables with param nodes, but that did not function.

How is it possible to set these special variables?

In the planetarygear- example you use the special variable $t for animation. So I think, you thought about the special variables.

Is there an undocumented scene node?

I have a few OpenSCAD programs, which use all of these variables for animation.I would like to port them to Graphscad.
